Analysis of Energy Consumption Causes of Fixed Speed Screw Air Compressor

As the basic product of industrial modernization, air compressor is an indispensable mechanical equipment in enterprise production. Air compressor is to convert electric energy into air kinetic energy, and its power consumption is very huge, especially the ordinary frequency machine.


Then about the Energy Consumption Causes of Fixed Speed Screw Air Compressor, we will discuss together:

1.Screw Air Compressor fixed speed startup impulse current is large

The fixed speed screw air compressor uses the star triangle starting mode and starts with 5-8 times the rated current. It has a big impact on the power grid, which is easy to cause instability of the power grid and threaten the operation safety of other electrical equipment, and there are abnormalities.

2. Power waste in loading and unloading

After the pressure of the traditional air compressor reaches the required working pressure, the pressure will continue to rise until the unloading pressure. If the air compressor only needs 6bar pressure, it must be played to 8bar, and then reduced to 6bar and then loaded, so there are two wastes. One is from 8bar to 6bar, the motor idling, causing serious no-load waste; The second is the waste of pressure difference from 6bar to 8bar. It was found that every 1bar of pressure increase consumes 7% more power, and 2bar of pressure consumes 14% more power.

In addition, due to the limitation of the fixed speed control mode, the motor can not be started and stopped frequently, so the motor still has to run no-load when the air consumption is little, which wastes a huge amount of electric energy.

3. The pressure is unstable and the adjustment is slow

The automation degree of fixed speed air compressor is low. The adjustment of output pressure is realized by the control of loading and unloading valve and regulating valve. The adjustment speed is slow, the fluctuation is large, the precision is low, and the output pressure is unstable, that’s why Energy Consumption Causes of Fixed Speed Screw Air Compressor.

4. Accelerated wear and tear, large maintenance

The working mode of fixed speed control determines that the loading and unloading valve must act repeatedly, and the parts are easy to age; Continuous fixed speed high-speed operation, not only loud noise, but also make bearing wear faster, equipment maintenance is large.

After the energy-saving transformation of the traditional air compressor, the air pressure output of the air compressor can match the air volume required by the user’s air system, achieve constant pressure gas supply, soft start operation, reduce the impact on the air compressor and other electrical equipment, enhance the stability of the air compressor, reduce the power expenditure, and realize the energy saving and consumption reduction of the air compressor
